I actually agree with you, but I can see that it's not very obvious from my snarky comment. I've always been a generalist, and if there's one thing I hope I can teach my children it's that it's possible to learn how to do, make and fix just about anything - probably with less effort invested than they'd expect.

I just think it's interesting how much more concerted effort, even over centuries, it takes us to figure out how to do these things on larger scales.
